THERMAL INFORMATION
The TS613 is housed in an Exposed-Pad plastic
package. As described on the figures below, this
package uses a leadframe upon which the dice is
mounted. This leadframe is exposed as a thermal
pad on the underside of the package. The thermal
contact is direct with the dice. This thermal path
provide an excellent thermal performance.
The thermal pad is electrically isolated from all
pins in the package. It can also be soldered to a
copper area of the PCB underneath the package.
Through these thermal paths within this copper ar-
ea, heat can be conducted away from the pack-
age. In this case, the copper area must be con-
nected to (-Vcc)
INTERMODULATION DISTORTION
The curves shown below are the measurements
results of a single operator wired as an adder with
a gain of 15dB.
The operational amplifier is supplied by a symmet-
ric 6V and is loaded with 25 .
Two synthesizers (Rhode & Schwartz SME) gen-
erate two frequencies (tones) (70 & 80kHz ; 180 &
280kHz).
An HP3585 spectrum analyzer measures the spu-
rious level at different frequencies.
The curves are traced for different output levels
(the value in the X ax is the value of each tone).
The output levels of the two tones are the same.
The generators and spectrum analyzer are phase
locked to enhance measurement precision.
